I don't trust “unlimited” wireless plans because they're all but unlimited and often come with a bunch of caveats one needs to consider carefully. The latest example: Sprint's newly announced data plan for tablets which promises unlimited 4G LTE data in exchange for $20 per month. So far so good, but the devil—as always—is in the detail.
If you take a closer look at the fine print, you soon realize that the plan limits video streaming to DVD-like 480p resolution, music streaming quality to 500kbps and your online gaming streams to up to 2Mbps.
